The campus was opened in 1953 as the successor to Los Angeles College. The school, which operated as a boarding school, offered 6 years of study, at which point graduates matriculated to St. John’s Seminary. In 1961, with the opening of the four-year St. John’s Seminary College in Camarillo, California, OLQA became a four-year high school institution.
Expansion and contraction (1963–1972)
Following a steady increase in students in the late 1950s and the resulting overcrowding, OLQA engaged in an ambitious expansion program, opening a second, adjacent campus in 1964 that effectively doubled the size of the school. The new campus contained eight dormitories; six class rooms, a separate chapel and a recreation room. With this addition, the original campus became known as the West Side, the new campus as the East Side. Although the overcrowding problem was solved, the school soon suffered a steep decline in the number of students, a reflection of national seminary trends following the Second Vatican Council. As a result, the East Side was last used as a separate campus in the 1967-1968 school year. Its use as classroom space continued until the 1970-1971 school year when it was closed. At the present time, the former East Side campus is used as the Administrative Office of the San Fernando pastoral region of the Los Angeles Archdiocese and as a preschool.
1973 to closure
With the departure of the Vincentian Fathers, OLQA entered a new era under the administration of diocesan priests appointed by the Cardinal Archbishop. During these years, Spanish replaced Latin in the curriculum by the late 1970s, and there were increased opportunities for off-campus community service. The athletics program was expanded with intramural competition for the first time in the school’s history. This era also saw a dramatic increase in minority enrollment that truly reflected the multicultural diversity of the Archdiocese of Los Angeles. After the establishment of the Diocese of Orange in 1976, the school served students from that diocese. By the 1994-1995 class, enrollment was down to 150 students and the campus was being shared with nearby Alemany High School, whose campus had been damaged in the Northridge earthquake. Due to the decline in enrollment, the lack of students advancing to the priesthood, and the increasing financial pressure on the archdiocese, the decision was made to close the campus, effective July 1, 1995.
